Dynamo light vs. Battery light, my first test
It is FINALLY warm enough to ride here in NYC again, and a beautiful day at that. Today I did my first commute since January and it was great.
But to the topic at hand, after I got home in the last daylight I waited for it to get completely dark to give my dynamo light a spin, and thought to put my Lezyne Super Drive on the bars. My dynamo light is the latest B&M Cyo Premium 80 lux model. The Lezyne is rated at 450 lumens.
Since the dynamo is always on, I started my ride down my Brooklyn street and it lights up the road nicely, but it is really hard to tell the reach as it doesn't throw light at the reflective signs. I then switched on the Lezyne and figured it would add to the light, but really I couldn't even tell it was on. I had to put my hand in front of it to see the beam, and it was bright. I switched off the B&M dynamo and I was completely surprised to see how little the Lezyne lights the road in comparison. I always thought the Lezyne was bright. I played around with it, aiming it differently, going from high to medium to low to flash. There is no comparison, the B&M is MUCH brighter with much more useful coverage. I'm as surprised by this result as all you disbelievers are.
My next comparison will be with my Chinese flashlight, which seems blindingly bright, but given the results above I don't think it will compare either. It was always just marginally brighter than the lezyne, with much less controlled light. I don't have one of the clones that everyone uses, so unless someone wants to join me in Brooklyn to give it a test in Prospect Park I won't do that comparison. I'd entertain any other lights to compare as well, if you have them. The other thing I'll do when I get a chance is to use my other new toy, my SJ1000 helmet mounted action cam to record this.
